Many given literature can only e to RGB values of the object color under test, while, if you can e to effectively measure the specific color of object color information, directly to the color of the display on the LCD screen in English, relatively more intuitive. To solve this problem, the paper work through prehensive investigation color identification principles and methods, finally determined used RGB230 color sensitive detector bined with a STC89C52 MCU to design the high accuracy, have higher stability, antiinterference and low price color detection system platform. Based on the success in the simulation, we under laboratory conditions, in accordance with the design scheme of color measurement system to build and debug, eventually be able to accurately identify red, green, blue colors. Key Words： RGB230。color detection system。colorimetry。 STC89C52 長春理工大學(xué) 光電信息學(xué)院 本科畢業(yè)設(shè)計 3 目錄 摘要 ................................................................................................................................. 1 Abstract ............................................................................................................................ 2 第 1 章 緒論 .................................................................................................................... 4 研究的目的及意義 .............................................................................................. 4 國內(nèi)外研究現(xiàn)狀 ................................................................................................. 4 課題研究內(nèi)容 ..................................................................................................... 4 第 2章 顏色測量的主要理論基礎(chǔ) ..................................................................................... 6 顏色匹配 ............................................................................................................ 6 色度學(xué) ............................................................................................................... 7 CIE標準色度學(xué)系統(tǒng) ........................................................................................... 7 第 3章 系統(tǒng)硬件電路設(shè)計 ............................................................................................... 9 LED補光電路 .............................................................................................. 9 RGB230色敏探測器 ............................................................................................10 I/V變換電路 ....................................................................................................10 .................................................................................................... 11 A/D轉(zhuǎn)換電路 ....................................................................................................12 ...........................................................................................................13 LCD液晶顯示 ....................................................................................................17 第 4章 系統(tǒng)軟件設(shè)計 .....................................................................................................19 程序流程設(shè)計 ....................................................................................................19 算法設(shè)計 ...........................................................................................................19 顏色檢測子程序 ................................................................................................20 顏色匹配子程序 ................................................................................................20 液晶顯示子程序 ................................................................................................20 第 5章 實驗測試與分析 ..................................................................................................21 系統(tǒng)軟硬件測試 ................................................................................................21 實驗結(jié)果分析 ....................................................................................................22 影響測量結(jié)果因素 .............................................................................................23 第 6章 結(jié)論 ...................................................................................................................25 參 考文獻 .........................................................................................................................26 致 謝 ..............................................................................................................................27 長春理工大學(xué) 光電
